Hush kit for the Pratt and Whitney JT8D-1 through -17 engines Two JT4As installed on a KLM DC-8. A hush kit is an aerodynamic device used to help reduce the noise produced by older aircraft jet engines. These devices are typically installed on older turbojet and low-bypass turbofan engines, as they are much louder than later high-bypass ...
Top: an assembled keyless chuck. This type of chuck is tightened by twisting the body using firm hand pressure only. While convenient, this feature can cause the chuck to tighten too much when high torque is applied. Bottom: the widely used keyed type of drill chuck with its key. The arbor is shown separately to the right. These chucks require ...
The tapered key is tapered only on the side that engages the hub. The keyway in the hub has a taper that matches that of the tapered key. Some taper keys have a gib, or tab, for easy removal during disassembly. The purpose of the taper is to secure the key itself, as well as to firmly engage the shaft to the hub without the need for a set screw.
The Dzus fasteners (gold coloured circular objects) fastening the cowling panels of the 1930s Hawker Hind.

The McDonnell Douglas YC-15 is a prototype four-engine short take-off and landing (STOL) tactical transport. It was McDonnell Douglas' entrant into the United States Air Force's Advanced Medium STOL Transport (AMST) competition to replace the Lockheed C-130 Hercules as the USAF's standard STOL tactical transport.
The large male taper takes a lathe chuck, which is retained by the large nut. A machine taper is a system for securing cutting tools or toolholders in the spindle of a machine tool or power tool. A male member of conical form (that is, with a taper) fits into the female socket, which has a matching taper of equal angle.
A jet aircraft (or simply jet) is an aircraft (nearly always a fixed-wing aircraft) propelled by one or more jet engines. Whereas the engines in propeller-powered aircraft generally achieve their maximum efficiency at much lower speeds and altitudes, jet engines achieve maximum efficiency at speeds close to or even well above the speed of sound .
